Business Licenses and Permits

After your Connecticut LLC is approved, you’ll need to comply with state and local government license and permit requirements.

Your requirements are determined by the industry you are in and where your business is located.

Not complying with license and permit requirements is risky and can result in penalties and fines, or worse, not being allowed to conduct business in the state.

Types of licenses you may need in Connecticut

Below are some license and permits examples:

  • Department of Revenue State Tax ID number
  • Business operation license/business privilege license
  • Sales tax license
  • Seller/reseller permit
  • Building permit
  • Health permit
  • Signage permit
  • Home occupation permit
  • Zoning and land use permits
  • Withholding taxes (if you have employees)

Industries that are more regulated usually have more requirements.
